FAQ
How does the Study Notes Organizer work?
Paste your notes as pipe-separated lines: subject|topic|title|content|tags|date. Tags are comma-separated within the tags cell (e.g. important,review,exam). The tool groups notes by subject → topic, builds a tag index, supports full-text search across title + content, filters by subject/tag, sorts by date, and exports as TXT, HTML (printable), Markdown, CSV, or JSON.
What input format does it expect?
One note per line, six pipe-separated fields: subject|topic|title|content|tags|date. Content fields can be wrapped in double quotes if they contain pipes (e.g. "See: chapter 3 | page 12"). Date is YYYY-MM-DD. Example: Biology|Cells|Mitochondria|Powerhouse of the cell|bio,cells|2024-09-12

(19) Tag cloud (top 10 by frequency). (20) Duplicate note detector (same title + subject).
Can I import these notes into Notion or Obsidian?
Yes. Use Download JSON to get a structured JSON file you can import into Notion or Obsidian. The Markdown export produces headers per subject → topic → note, which Obsidian reads natively.
Is my data sent anywhere?
No. All parsing, grouping, search, and export runs 100% client-side in your browser. History is stored in localStorage on this device only. No notes ever leave your computer.
